Today on the program we’re talking about black holes — places in space where the pull of gravity is so strong that light can’t escape. But gravity is just one force at play in a black hole, and our guests say that if you want to understand black holes, gravity might not be the best place to start.

All across the world’s oceans, you can find creatures known as larvaceans – free-swimming invertebrates with a superpower, of sorts.

We all know that exercise is good for us — that’s sort of a given. But have you ever thought about whether one sort of exercise is better than others? Is cycling better than golf? Is golf better than baseball? Is running really the gold-standard for exercise that everyone thinks it is? Demographic sociologist Connor Sheehan thinks he’s got the answers — and they might surprise you.

As it was becoming clear that the United States was going to be one of the epicenters of the COVID-19 pandemic, I was asked to talk to a group of climate adaptation students about crisis communication — and I worried at first that I wouldn’t be able to draw lines between two very different crises. It turns out, though, that these crises have a lot in common.

We’re talking to three researchers who came together, across very different disciplines, to try to do something to address a problem that affects millions of American children: how can we make the experience of visiting an incarcerated parent a little bit less traumatic?

We’re talking about an ancient ancestor of modern anchovies, a fearsome fish that swam the seas about 55 million years ago — and, like so many other ancient creatures, it was a lot scarier back then than it is now.

Since the unification of the northern and southern dynasties in China 1,500 years ago, Chinese chefs have been making fried rice. And if you have never stopped to watch a master chef go to work preparing this dish, you are missing out.

We all know that meals bring people together. But when it comes to building trust and cooperation, it turns out that not all meals are created equal. And this week on the program, we're talking to a researcher whose work has shown that people eating from shared serving plates are more likely to work together rather than compete.

We're talking to two mathematicians who have harnessed the power of numbers to solve one of the biggest challenges of the kitchen: how to cook a perfect steak. And yes, this is a fun and whimsical use of math, but it's also a true accomplishment in macromolecular science.

Today on the program, we are talking to Jill Suitor, one of the founders of a nearly 20 year old study focused on the relationships parents have with their adult children and, in particular, their favorite children. Yes, it's true parents have favorites. And children are often wrong about who that favorite is.
